The crc32 acceleration in the inside-secure driver is accessible only as an asynchronous hash. However, there seems to be no corresponding user of crc32 in the kernel that supports asynchronous hashes. Therefore, this code seems to be unused. The patch that added this code provided no justification for its inclusion. All devicetree bindings for this accelerator are for arm64; arm64 CPUs often have CRC or PMULL instructions, which already accelerate crc32 very well. And these actually work with the crc32 users in the kernel, unlike this driver which doesn't. Remove this unnecessary code.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
